MOP-WRINGER.

$PECIFICATION forming part of Letters Patent No. 541,591, dated June 25, 1895.

Application filed March 18, 1 8 95.

Serial No. 542,080. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR M. BURNHAM, a citizen of the United States of America, resid ing at Gardiner, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in MOp /Vringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

My invention relates to improvements in a combined pail and mop Wringer, and more particularly to improvements in and upon the mop wringer described in Letters Patent No. 447,732, issued -to Walter S. Jarboe March 3, 1891. .In said Jarboe patent the wringer rolls are turned by a lever by means of aV shaped spring connecting said lever with the standards upon which said wringer rolls are mounted. In actual use it is found that when the rolls are brought together by pressing down the lever, the rolls assume a practically unyielding-condition and are incapable of adjnstin g themselves to the different thicknesses of the mop or to bunches which may be in the mop.

The present invention consists in certain improvements which render the wringer rolls capable of a yielding adjustment independently of the lever and V-shaped springs which operate saidrolls. a

It further consists in certain details of construction which will be hereinafter fully described and specifically claimed.

In the drawings herewith accompanying and forming a part of this application, Figure 1 is an isometrical view of a pailand mopwringer embodying my invention, and Fig. 2 is a vertical longitudinal section of the same.

In said drawings a represents the pail; b, a frame work rigidly attached to the same at or near the bottom. Pivotally attached to said frame or to the pail is a foot lever cl.- Journaled in the top of the pail in any convenient manner are rods e having the arms f rigidly attached to the ends thereof outside of the pail and extending upwardly at right angles to said rods. Connecting these endsf and said foot lever are V-shaped springs g which tend to turn said rods away from each other.

Journaled on each of said rods is a support ing frame h free to turn thereon except as otherwise limited. Mounted in the frames are the wringer rolls '6. The frames h are held in a normally fixed position relative to rods 6 by means of coil springs j mounted on said rods e and lugs rigidly set on said rod. Connecting the ends of said frames is a cross bar Z. The frames and rolls are rigidly held against rotation toward each other on said rods by means of lugs 70 and are yieldingly held against rotation on said rods away from each other by coil springsj. Springsj at the center lie inside of said lugs and have their extremities n bent upwardly and in contact with the frames which support said wringer rolls. The coil springs are made strong to hold the rolls against backward movement but are capable of yielding under unusual pressure to permit the rolls to pass over bunches in the mop, the frames which support the rolls turning on said rods and permitting the mop to be drawn through without removing the foot from the lever, as is necessary in the Jarboe wringer.

Pivotally mounted at the sides of the pail are swinging clamps 0 adapted to swing toward each other. Said clamps have lugs 19 extending out over the sides of the pail and into the path of the turned up ends of the rods 6 so that when the lever is pressed down and the rolls brought together, said ends engage said lugs and swing said clamps toward each other, and then hold the mop between the rolls.

I claim.-

1. In combination, a pail, rods journaled in said pail and provided with cranks turned upwardly outside of said pail, means for rotating said rods, frames pivotally mounted on said rods, Wringer rolls mounted on said frames, said frames being capable of backing movement on said rods, and springs tending to hold said frames against backward movement, substantially as and for the purposes set forth.

2. In combination, a pail, rods journaled in said pail and provided with cranks turned upwardly outside the pail, a foot lever attached to the side of the pail, V-shaped springs connecting said lever and saidupturned ends, frames mounted on said rods and capable of backward movement independently of said rods, springs tending to hold said frames against backward movement, lugs rigidly set on said rods and adapted to limit the forward movement of said frames on said rods, and wringer rolls mounted on said frames, substantially as and for the purposes set forth.

3. In combination, a pail, rods journaled in said pail and provided with cranks turned upwardly outside of said pail, means for rotating said rods, wringer rolls mounted on said rods inside said pail, side clamps pivotally attached to the inside of the pail, and having lugs extending over the sides of the pail and into the path of the turned up ends of said rods, substantially as and for the purposes set forth.

In testimony whereof I affix my signature, in presence of two witnesses, this 19th day of February, 1895.

ARTHUR M. BURNIT AM.
